Answer:

x-intercept ( 18/5, 0) y-intercept: (0, -2)

Step-by-step explanation:

-5x+9y= -18

Find x-intercept by letting y = 0.

-5x + 9*0 = -18

-5x = -18

x = 18/5

Find y-intercept by letting x=0

-5*0 +9y = -18

9y =-18

y = -2

Hi please help me as soon as possible:

sammy [17]

Answer:

Percentage = 14.2%

Step-by-step explanation:

Given the following data;

Cost of plane ticket = £588

Airport tax = $130

£1 = $1.34

To find the percentage of the total cost spent on airport tax;

First of all, we would convert the ticket cost in pounds (£) to dollars ($).

Cost of plane ticket = £588 to $ = 588 * 1.34 = $787. 92

Total cost = Cost of plane ticket + Airport tax

Total cost = 787. 92 + 130

Total cost = $917.92

$Percentage \; cost = \frac {130}{917.92} * 100$

$Percentage = 0.1416 * 100$

Percentage cost = 14.16 to 1 d.p = 14.2%

Therefore, the percentage of the total cost spent on airport tax by Rimo is 14.2 percent.

Three good friends are in the same algebra class. Their scores on a recent test are three consecutive even integers whose sum is

klio [65]

Let the lowest score be x.

The 3 consecutive even scores are:

1st score = x

2nd score = x + 2

3rd score = x + 4

Sum of their score is 270:

x + (x + 2) + (x + 4) = 270

Solve x:

x + (x + 2) + (x + 4) = 270

x + x + 2 + x + 4 = 270

3x + 6 = 270

3x = 264

x = 88

Find their scores:

1st score = x = 88

2nd score = x + 2 = 88 + 2 = 90

3rd score = x + 4 = 88 + 4 = 92

Answer: The scores are 88, 90 and 92

a specific shade of green glaze requires 5 parts blue to 3 parts yellow. a glaze mixture contains 25 quarts of blue and 9 quarts

-BARSIC- [3]

if you are multiplying by 5, then the blue needs to be 25 quarts and the yellow needs to be 15 quarts not 9. If you are multiplying by 3 then it would be 9 quarts yellow and 15 quarts blue. hope this helps :)
